Celebrate the Celestial Event of the Century!

The Chester County Library has joined more than 1,000 libraries across the country to participate in the celestial event of the century, the August 21, 2017 Solar Eclipse. During this national event, the shadow of the moon will sweep across the United States in a narrow band from the Pacific Ocean to the Atlantic Ocean in a spectacle that hasn't occurred in decades. In fact, the last total solar eclipse for the United States was nearly 40 years ago. The rest of the U.S. and North America will see a partial eclipse, with the Moon covering up only part of the Sun. It is aptly named the Great American Eclipse. 

This will be a great opportunity for our community to celebrate culminating in the eclipse viewing event on August 21, 2017 at the Exton Park Site, 132 Church Farm Lane, Exton, PA from 1:30 p.m. until 3:30 p.m. Solar Eclipse Viewing Glasses will be distributed to the first 100 participants. Register here for the viewing party. 

Leading up to the Great American Eclipse, we will welcome NASA Solar System Ambassador, Dennis O'Leary on Wednesday, August 9th at 7 p.m. at the Chester County Library. Dennis will discuss lunar and solar eclipses. Discover why they form, safe viewing practices and what you can to expect see in our area and at totality. Register here for this exciting program! 

Join other space fans and view the film Apollo 13 on Wednesday, August 2 at 6:00 p.m. and meet Mather Planetarium Director, Dr. Karen Schwarz on August 17th. For a full schedule of events, visit or contact Pam Marquette at or 610.280.2642.
